AKjDPG 1: PhD Focus Session: Photoluminescence of halide perovskites: What does it tell us and what not? (joint session DS/HL/AKjDPG)

Dienstag, 2. April 2019, 09:30–13:15, H32

Perovskite Solar Cells (PSCs) have recently emerged as a new research field due to their rapid increase in power conversion efficiency. Many research groups formerly working in other fields such as in DSSC, organic solar cells and thin film solar cells, quantum dots, single molecules have jointly created a new research field. Photoluminescence spectroscopy is a technique used rather widely in all of these fields as a simple standard method. Applying specific models and theory, photoluminescence can however be converted into an advanced characterization technique. The models and analysis tools used for this have been unique to the specific fields so far and now tend to collide when PSCs are measured and analysed.
This symposium therefore aims to give a brief overview of advanced models and analysis tools which allow a more nuanced interpretation of photoluminescence emission of perovskite solar cell materials. In a mix of introductory talks, invited expert talks and contributed talks we will explore how certain models have been used to analyse PSCs and argue why and under what conditions a certain model can or cannot be applied to perovskite solar cells.
